Just for information, this RAID controller is sold separately on Dell online store, like Adapted or LSI Logic RAID controllers: http://accessories.us.dell.com/sna/productdetail.aspx?c=us&l=en&cs=04&sku=341-5900&baynote_bnrank=2&baynote_irrank=0&~ck=baynoteSearch
A reply from Intel staff would be really appreciated!
Thanks in advance!
I just found the solution on a forum:
SMBus Issue with Intel Chipsets
These cards are known to have some compatibility issues with Intel chipsets. However, they are known to work with NVIDIA motherboards fine. The issue stems from a System Management Bus (SMBus) conflicting with the motherboard's memory detection. SMBus is simple signal to provide the motherboad some basic device information and control. Symptoms of the conflict includes improperly reported RAM sizes and POST errors.
The trick is just to physically disable the SMBus signal. It is composed of just two pins B5 (SMCLK, SMBus clock) and B6 (SMDAT, SMBus data). These two pins need to be covered by tape or nail polish. On the top side of the card, they are the 5th and 6th PCIe pins from the left. You can see the pins covered as seen below:
This problem is present on many Intel boards, and never resolved...
